On a weighted quasi-residual minimization strategy of the QMR method for solving complex symmetric shifted linear systems

T. Sogabe, T. Hoshi, S. -L. Zhang +1

We consider the solution of complex symmetric shifted linear systems. Such systems arise in large-scale electronic structure simulations and there is a strong need for the fast sol…
